For the Removal of Reactive Red 4 by using Activated Carbon - MnO2-Nano Composite: Different Isotherm Studies

This paper presents the feasibility of removal of Reactive dye Reactive Red 4 from aqueous solutions by using a low cost AC-MnO2-NC. The effects of agitation time, adsorbent dose, initial dye concentration, pH and temperature were examined. Langmuir, Freundlich and Tempkin isotherms were also studied. Adsorbent used in this study are characterized by FT-IR, XRD and SEM analysis.
